How does the RAID work, i.e. I would like to have 2 mirrored drives in PROD and have a 3rd backup in a safe location and periodically swap them out.

It would be far easier to back up to an external drive and keep it off site. This saves the very long drive rebuilding process. You really should have more than one backup especially for important data, photos etc. RAID is not the same as backup.

Not sure why you would want to do it that way. With mirrored drives you already have drive redundancy. If a drive goes bad, pull it out and put in the new drive. There are better ways to provide for offsite backup than to keep pulling a drive and having the raid rebuild itself.

I have 3 TB drives in a raid 5 configuration. No issues yet. We use it primarily for time machine backups.

I believe by default they come in a RAID 1, which would give you 2TB of total storage. If you set it to RAID0, you'll get use of all 4TB (probably 3.6 or so useable) but you will not have redundancy.

You can configure the drive however you like (raid 1 or 0) and it works stand-alone or daisy chained. It's a very flexible and reliable drive.

I'm not sure either. I've only used mine for 1 drive. I doubt it would work for 2 at once. You would probably need 2 adapters and some software that could reconstruct the data, which is shared between the 2 raid 0 drives.

This something I do not know.. I have 2 x 2TB in mine set up as Raid 1 so they image each other. I also received my first one that was defective, but after using Zyxel's RMA and replacement under warranty, the second one I received is working fine.

It depends on the type of raid setup you use. There is a hybrid setup that makes use of all the drives and maximizes the space available. This way you can have different size drives. I accepted this as the default. I can't verify how it works though as all my drives are the same size. It's a bit slower than I would have liked also, but hey, it does the job.

You can, just make sure when u make changes back up your data first..... You can loose it, upon moving from say Raid 0 to Raid 5.

Using X-RAID is the only way to make that work. But you are limited to 1 volume, if you want more than 1 volume you would turn off X-RAID but you cant go back without reformatting your drives. X-RAID will manage your redundancy

You probably mean RAID 0 because RAID 1 is mirroring. I had it configured as RAID 10, it worked for a while until it failed but not because it was part RAID configuration.

I don't know how to do raid. I just keep all my music and moive in it so I can watch it in every room in my house. I have a 4TB drive in it.

With the Synology RAID option you can start with the 3TB drives and add larger ones later. You just can't anything of smaller size than the drives used to create the array.

No it does not. It has a feature called "folder duplication" which makes sure folders you identify are copied across multiple drives. Sure, it doesn't offer real-time redundancy, but it is far more simple than RAID and is easier to manage.

You can add drives as you need them. The drives can be of mixed sizes too for the hybrid raid configuation; however, I recommend you try to keep to one drive size so select your initial drives with the thought of expanding later.

While I think the MAC Pro decision is questionable ;) I do recommend the LaCie. I have more than one drive. there are different ways to safeguard the data, if you use mirroring you are basically duplicating (backing up on the fly) everything that you write of the drive and if the drive fails you go to the mirror, with this option you utilize only 50% of the drive storage.the other option (and the one I use) is RAID 5. you use 80% of the storage capacity but if a drive fails, you can still read the date normally till you replace it. if more than one drive fail at a time then you are out of luck and should never buy lottery tickets :) While I think the MAC Pro decision is questionable ;) I do recommend the LaCie.

I backup critical files to an external 3TB HDD plugged into the unit and have a remote DS212 at my in-laws house with 3TB RAID 1. The remaining 7TB is data I could recreate, but it would be more painful. Just going with RAID 5 and no other backups is a poor decision, especially if you are a business.

RAID 0,1 and SHR (Synology Hybrid Raid). With only 2 drives you can't get 5.
